Umm…You Can Get a Body Like Kristin Cavallari’s in 20 Minutes?

When I normally see a size zero movie star, I usually think, meh, they have personal trainers and all that stuff. That’s the only way they can maintain such a svelte figure. Then I see movie stars who have returned to a size zero body maybe six weeks after giving birth, and I think – how is that possible? Do they ONLY spend their time working out and eating healthy? That’s the only solution right?….
